Two immiscible Newtonian fluids are contained between infinite parallel plates. The plates are separated by distance 4h, and the top fluid layer thickness is h. The bottom fluid layer thickness is 3h. The viscosity of the bottom fluid is three times that of the top fluid. If the lower plate is stationary and the upper plate moves at constant speed of 40 m/s, what is the velocity at the interface
